I'm new to the scene. If a raid isn't a backup, then what is?
It provides redundancy in case a drive fails, but there's no protection if you accidentally delete a file. That's why they say "RAID is not a backup."
Raid can be redundancy, backup is when the data is offsite(be it cloud or drive offsite) to prevent situations like fires or floods from destroying your data. If all your data is in the same place, its still not safe
Something where your files won't disappear due to a single errant command or ransomware.
